Abstract: The Aberrant and Diminished Activity Detector Apparatuses, Methods and Systems (“DAD”) transforms abnormal financial or behavioral pattern and enrollment request message inputs via DAD components into alert outputs that may be sent to trusted parties or caregivers, in order to reduce and prevent fraudulent financial transactions that target the elderly or impaired individuals. A subject is enrolled in the DAD system via an enrollment component via enrollment information provided by one of the subject and an observer. The DAD system determines abnormal transaction indicators for the subject from at least one of: historical financial transaction patterns of the subject, abnormal behavior patterns of the subject and predictive indicators derived from historical fraudulent financial data of a population. Alarm thresholds based on the abnormal transaction indicators are determined.

Abstract: The present invention provides a hard disk drive laser assisted magnetic recording system including a semiconductor laser and magnetic write coil integrally formed into a slider. The slider preferably includes a perpendicular magnetic recording section adjacent a laser section. The laser section may form an air bearing surface of the slider. During recording operations, laser radiation from the laser section heats a region of the magnetic recording media in order to reduce its coercivity.

Abstract: The present invention is an apparatus for generating the focus, tracking, and data signals for a magneto-optical data storage device, using a Wollaston prism and a photodetector having four subdetectors. A reflected beam from a disk is directed into the Wollaston prism and is split into two beams, with the beams oriented substantially parallel to the in-track direction. The beams from the prism are collected asymmetrically by both subdetectors of first and second pairs of subdetectors, so that one subdetector in each pair collects more light than the other, and two diagonally opposite subdetectors receive more light than the other two subdetectors. Two focus composite signals are generated by adding the signals from diagonally opposite subdetectors, and the focus error signal is generated by subtracting one focus composite signal from the other.
